EAST BAY TOWNSHIP -- The pilot of a small plane that crashed in northern Michigan, apparently killing his wife, lost his daughter in a 2006 Indiana plane crash that killed five Indiana University students.

Authorities say Yatish Joshi, 51, of South Bend, Ind. was in critical condition with burns following the Thursday night crash of the twin-engine Cessna 310. It went down in a densely wooded swamp in East Bay Township.

Officials still haven't positively identified a body found near the wreckage. But Grand Traverse County Sheriff Scott Fewins said Joshi told authorities he was flying with his wife, Louise Addicott.

Joshi's daughter, 24-year-old Georgina Joshi, died when the plane she was piloting crashed in April 2006 in Indiana.

Glenda Lamont, who has been Joshi's accountant for more than 10 years, said the couple had an incredibly strong connection. She said Addicott and Joshi grew closer after Georgina Joshi's death.

"You can imagine how horrifying this is," Lamont told the Traverse City Record-Eagle.

The crash happened while the plane was nearing Cherry Capital Airport in Traverse City. Joshi's plane left South Bend Regional Airport earlier in the day, the Federal Aviation Administration said.

The couple owned a condominium at Crystal Mountain, Lamont said.

The cause of the crash was under investigation.

In the 2006 crash that killed Georgina Joshi, the National Transportation Safety Board said pilot error was the likely cause. The single-engine Cessna wend down about half-mile short of an airport in Bloomington, Ind.

All killed were graduate students in IU's music school and were returning to Bloomington after a concert rehearsal in West Lafayette.
